Which statement is true if the hrxn of a reaction is positive

Answer : The reaction is endothermic in nature.

Explanation : A system of reactants which absorbs heat from the surroundings in an endothermic reaction has a positive ΔH reaction value, as the enthalpy of the products is higher than the enthalpy of the reactants of the system.

As the enthalpies of these reactions are greater than zero, they are called as endothermic reactions. Which absorbs the heat during the chemical reactions.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
